Get started Getting started with Atomist atomist, software supply chain, vulnerability scanning, tutorial 2

{% include atomist/disclaimer.md %}

To get started with Atomist, you'll need to:

  • Connect Atomist with your container registry
  • Link your container images with their Git source

Before you can begin the setup, you need a Docker ID. If you don't already have one, you can register here{: target="blank" rel="noopener" class=""}.

Connect container registry

This section describes how to integrate Atomist with your container registry. Follow the applicable instructions depending on the type of container registry you use. After completing this setup, Atomist will have read-only access to your registry, and gets notified about pushed or deleted images.

Using Docker Hub? 🐳

If you are using Docker Hub as your container registry, you can skip this step and go straight to linking images to Git source. Atomist integrates seamlessly with your Docker Hub organizations.

  • Amazon
  • GitHub
  • Google
  • JFrog

When setting up an Amazon Elastic Container Registry (ECR) integration with Atomist, the following AWS resources are required:

  • Read-only Identity Access Management (IAM) role, for Atomist to be able to access the container registry
  • Amazon EventBridge, to notify Atomist of pushed and deleted images

This procedure uses pre-defined CloudFormation templates to create the necessary IAM role and Amazon EventBridge. This template protects you from confused deputy attacks{: target="blank" rel="noopener" class=""} by ensuring a unique ExternalId, along with the appropriate condition on the IAM role statement.

  1. Go to https://dso.docker.com and sign in using your Docker ID credentials.

  2. Navigate to the Integrations tab and select Configure next to the Elastic Container Registry integration.

  3. Fill out all the fields, except Trusted Role ARN. The trusted role identity is known only after applying the CloudFormation template.

    Choose basic auth credentials to protect the endpoint that AWS uses to notify Atomist. The URL and the basic auth credentials are parameters to the CloudFormation template.

  4. Now create the CloudFormation stack. Before creating the stack, AWS asks you to enter three parameters.

    • Url: the API endpoint copied from Atomist
    • Username, Password: basic authentication credentials for the endpoint. Must match what you entered in the Atomist workspace.

    Use the following Launch Stack buttons to start reviewing the details in your AWS account.

    Note

    Before creating the stack, AWS will ask for acknowledgement that creating this stack requires a capability. This stack creates a role that will grant Atomist read-only access to ECR resources.

    confirm

    Region ecr-integration.template
    us-east-1 Launch Stack
    us-east-2 Launch Stack
    us-west-1 Launch Stack
    us-west-2 Launch Stack
    eu-west-1 Launch Stack
    eu-west-2 Launch Stack
    eu-west-3 Launch Stack
    eu-central-1 Launch Stack
    ca-central-1 Launch Stack
    ap-southeast-2 Launch Stack

  5. After creating the stack, copy the Value for the AssumeRoleArn key from the Outputs tab in AWS.

  6. Paste the copied AssumeRoleArn value into the Trusted Role ARN field on the Atomist configuration page.

  7. Select Save Configuration.

    Atomist tests the connection with your ECR registry. A green check mark displays beside the integration if a successful connection is made.

To integrate Atomist with GitHub Container Registry, connect your GitHub account, and enter a personal access token for Atomist to use when pulling container images.

  1. Go to https://dso.docker.com and sign in using your Docker ID credentials.

  2. Connect your GitHub account as instructed in the GitHub app page.

  3. Open the Integrations tab, and select Configure next to the GitHub Container Registry in the list.

  4. Fill out the fields and select Save Configuration.

    Atomist requires the Personal access token for connecting images to private repositories. The token must have the read:packages scope{: target="blank" rel="noopener" class=""}.

    Leave the Personal access token field blank if you only want to index images in public repositories.

Setting up an Atomist integration with Google Container Registry and Google Artifact Registry involves:

  • Creating a service account and grant it a read-only access role.
  • Creating a PubSub subscription on the gcr topic to watch for activity in the registry.

To complete the following procedure requires administrator's permissions in the project.

  1. Set the following environment variables. You will use them in the next steps when configuring the Google Cloud resources, using the gcloud CLI.

    export SERVICE_ACCOUNT_ID="atomist-integration" # can be anything you like
export PROJECT_ID="YOUR_GCP_PROJECT_ID"

  2. Create the service account.

    gcloud iam service-accounts create ${SERVICE_ACCOUNT_ID} \
    --project ${PROJECT_ID} \
    --description="Atomist Integration Service Account" \
    --display-name="Atomist Integration"

  3. Grant the service account read-only access to the artifact registry.

    The role name differs depending on whether you use Artifact Registry or Container Registry:

    • roles/artifactregistry.reader for Google Artifact Registry
    • roles/object.storageViewer for Google Container Registry
    gcloud projects add-iam-policy-binding ${PROJECT_ID} \
    --project ${PROJECT_ID} \
    --member="serviceAccount:${SERVICE_ACCOUNT_ID}@${PROJECT_ID}.iam.gserviceaccount.com" \
    --role="roles/artifactregistry.reader" # change this if you use GCR

  4. Grant service account access to Atomist.

    gcloud iam service-accounts add-iam-policy-binding "${SERVICE_ACCOUNT_ID}@${PROJECT_ID}.iam.gserviceaccount.com" \
    --project ${PROJECT_ID} \
    --member="serviceAccount:atomist-bot@atomist.iam.gserviceaccount.com" \
    --role="roles/iam.serviceAccountTokenCreator"

  5. Go to dso.docker.com{: target="blank" rel="noopener" class=""} and sign in with your Docker ID credentials.

  6. Navigate to the Integrations tab and select Configure next to the Google Artifact Registry integration.

  7. Fill out the following fields:

    • Project ID is the PROJECT_ID used in earlier steps.
    • Service Account: The email address of the service account created step 2.

  8. Select Save Configuration. Atomist will test the connection. Green check marks indicate a successful connection.

    GCP configuration successful{: width="700px"}

    Next, create a new PubSub subscription on the gcr topic in registry. This subscription notifies Atomist about new or deleted images in the registry.

  9. Copy the URL in the Events Webhook field to your clipboard. This will be the PUSH_ENDPOINT_URI for the PubSub subscription.

  10. Define the following three variable values, in addition to the PROJECT_ID and SERVICE_ACCOUNT_ID from earlier:

    • PUSH_ENDPOINT_URL: the webhook URL copied from the Atomist workspace.
    • SERVICE_ACCOUNT_EMAIL: the service account address; a combination of the service account ID and project ID.
    • SUBSCRIPTION: the name of the PubSub (can be anything).
    PUSH_ENDPOINT_URI={COPY_THIS_FROM_ATOMIST}
SERVICE_ACCOUNT_EMAIL="${SERVICE_ACCOUNT_ID}@${PROJECT_ID}.iam.gserviceaccount.com"
SUBSCRIPTION="atomist-integration-subscription"

  11. Create the PubSub for the gcr topic.

    gcloud pubsub subscriptions create ${SUBSCRIPTION} \
  --topic='gcr' \
  --push-auth-token-audience='atomist' \
  --push-auth-service-account="${SERVICE_ACCOUNT_EMAIL}" \
  --push-endpoint="${PUSH_ENDPOINT_URI}"

When the first image push is successfully detected, a green check mark on the integration page will indicate that the integration works.

Atomist can index images in a JFrog Artifactory repository by means of a monitoring agent.

The agent scans configured repositories at regular intervals, and send newly discovered images' metadata to the Atomist data plane.

In the following example, https://hal9000.atomist.com is a private registry only visible on an internal network.

docker run -ti atomist/docker-registry-broker:latest\
  index-image remote \
  --workspace AQ1K5FIKA \
  --api-key team::6016307E4DF885EAE0579AACC71D3507BB38E1855903850CF5D0D91C5C8C6DC0 \
  --artifactory-url https://hal9000.docker.com \
  --artifactory-repository atomist-docker-local \
  --container-registry-host atomist-docker-local.hal9000.docker.com
  --username admin \
  --password password
Parameter Description
workspace ID of your Atomist workspace.
api-key Atomist API key.
artifactory-url Base URL of the Artifactory instance. Must not contain trailing slashes.
artifactory-repository The name of the container registry to watch.
container-registry-host The hostname associated with the Artifactory repository containing images, if different from artifactory-url.
username Username for HTTP basic authentication with Artifactory.
password Password for HTTP basic authentication with Artifactory.

Link images to Git repository

Knowing the source repository of an image is a prerequisite for Atomist to interact with the Git repository. For Atomist to be able to link scanned images back to a Git repository repository, you must annotate the image at build time.

The image labels that Atomist requires are:

Label Value
org.opencontainers.image.revision The commit revision that the image is built for.
com.docker.image.source.entrypoint Path to the Dockerfile, relative to project root.

For more information about pre-defined OCI annotations, see the specification document on GitHub{: target="blank" rel="noopener" class=""}.

You can add these labels to images using the built-in Git provenance feature of Buildx, or set using the --label CLI argument.

Add labels using Docker Buildx

Beta

Git provenance labels in Buildx is a Beta feature.

To add the image labels using Docker Buildx, set the environment variable BUILDX_GIT_LABELS=1. The Buildx will create the labels automatically when building the image.

export BUILDX_GIT_LABELS=1
docker buildx build . -f docker/Dockerfile

Add labels using the label CLI argument

Assign image labels using the --label argument for docker build.

docker build . -f docker/Dockerfile -t $IMAGE_NAME \
    --label "org.opencontainers.image.revision=10ac8f8bdaa343677f2f394f9615e521188d736a" \
    --label "com.docker.image.source.entrypoint=docker/Dockerfile"

Images built in a CI/CD environment can leverage the built-in environment variables when setting the Git revision label:

Build tool Environment variable
GitHub Actions {% raw %}${{ github.sha }}{% endraw %}
GitHub Actions, pull requests {% raw %}${{ github.event.pull_request.head.sha }}{% endraw %}
GitLab CI/CD $CI_COMMIT_SHA
Docker Hub automated builds $SOURCE_COMMIT
Google Cloud Build $COMMIT_SHA
AWS CodeBuild $CODEBUILD_RESOLVED_SOURCE_VERSION
Manually $(git rev-parse HEAD)

Consult the documentation for your CI/CD platform to learn which variables to use.

Where to go next

Atomist is now tracking bill of materials, packages, and vulnerabilities for your images! You can view your image scan results on the images overview page{: target="blank" rel="noopener" class=""}.

Teams use Atomist to protect downstream workloads from new vulnerabilities. It's also used to help teams track and remediate new vulnerabilities that impact existing workloads. The following sections describe integrate and configure Atomist further. For example, to gain visibility into container workload systems like Kubernetes.
